Process for coating refractory material

The invention relates to a method for producing a coating on a refractory Component, wherein as a coating material, a noble metal alloy refractory to Component is applied. It has as its object to provide a faster and more cost-effective A process for the production of coatings on components for the glass industry to provide. The problem is solved for the method in that the noble metal alloy under others have a share of an oxidizable substance, wherein the oxidizable substance is formed from boron and / or phosphorus and / or antimony and / or arsenic, thatthe refractory component and the coating in an oxygen-containing atmosphere at least once to a temperature T greater than or equal to the liquidus TL the noble metal alloy, thatthe oxidizable substance is oxidized in the process and arisen oxide at least partially is evaporated, and thatthe temperature T is maintained until the fraction of oxidizable substance in the Coating <0.1 at% and the coated refractory component then is cooled.
